Highend Manual update problem

Hi,

When I try to delete the Highend theme I get this message: Deletion failed: The requested theme does not exist.

Visual composer wasn’t loading the page for edit, that’s why I enter the forum and find about 3.2 update. I think maybe this is the problem.

I am using a child theme, do i need to do something different? My current version is 1.0.

Thanks in advance for your support.
